In the end, a lot of the season felt very reactionary. The attitude of "synching up with canon" seems directed squarely at the haters who think the show is nothing but one massive canon violation and they were desperate to gain their trust.
And not for nothing but the idea of ending the season like this didn't make a lot of sense to me. This is a mentality more suited if this were the end of the series. There's still a good nine years before the official start of TOS. It's not as if it begins the next day. The series is not overlapping with TOS in any way, if you consider TOS strictly as what was aired from 1966-1969.
But, hey, if they want to go into the future because it will free them from having to adhere to canon, then, awesome. Go for it. I'm excited to see what the future holds. I just didn't think it was wholly necessary. There are plenty of stories they can tell in the 23rd century without viewing canon as some massive storm cloud threatening to rain hell down on them if the slightest perceived slip is made.
